Science Plan - Adult 1-6 with Chicken
Summary
Hill’s Science Plan – Adult 1-6 with Chicken is a dry formula for adult cats aged 1–6, designed to support daily maintenance with balanced protein, fat, and minerals.
The first ingredient is chicken and turkey meal, listed at 26% with chicken at 16%, supplying concentrated animal protein to help maintain lean muscle and overall body strength.
At 31.9% crude protein and 19.7% fat, the diet delivers the amino acids and energy adult cats need, helping sustain activity levels and healthy body condition when portioned appropriately.
Carbohydrates at 37.5% come mainly from wheat, maize, and broken rice, providing readily available energy but also increasing overall starch content.
Fish oil contributes long-chain omega-3s, and the declared omega-3 (0.42%) and omega-6 (3.04%) levels support skin and coat health and a balanced inflammatory response.
Calcium at 0.75% and phosphorus at 0.74% work together to support bone and dental health in adult cats.
Magnesium at 0.082% and sodium at 0.42% reflect a controlled mineral profile that supports urinary tract health and normal fluid balance.
Dried beet pulp provides fermentable fiber to nourish beneficial gut bacteria and promote regular stools despite a low crude fiber level (1.4%).
Antioxidant support includes vitamin E (722 IU/kg), vitamin C (115 ppm), and beta-carotene (2.84 ppm), which help protect cells from oxidative stress.
Taurine at 0.19% supports normal heart function and vision, a non-negotiable requirement for feline health.

How the score is calculated?
The actual calculation of the score is based on sophisticated and advanced algorithm that takes into account multiple parameters.
To simplify the explanation, the calculation is based on three main criteria:
(1) Amount of protein (more is better)
(2) Amount of carbohydrates (less is better)
(3) Quality and source of ingredients.
Based on that 3 main criteria, 9 score calculation rules are used to compare the different foods.
One major assumption is that the closer an ingredient is to the top of the ingredient list, the greater its relative weight and contribution to the food.
In general, cat food is composed of protein, fats, carbohydrates, fibers, vitamins, and minerals.
Protein is the most important component in a cat's diet, and cats primarily get their protein from animal meat.
Fat is a primary source of energy and essential fatty acids.
Carbohydrates are controversial in a cat's diet, as cats are obligate carnivores and typically consume very few carbohydrates.
Fibers play an important role in digestion and food absorption, and vitamins and minerals are essential for different organism functions.
Dry matter values are used to compare the amount of nutrients in different cat foods. This means that moisture is excluded from the equation to provide a more accurate comparison.
Putting all of these and more into a formula results in a product score.
The maximum score a cat food can receive is 100. Points are added or removed based on the score calculation rules.
